The Avengers: Age of Ultron star loves his 2-year-old so much, in fact, that everything else takes a backseat to their relationship! On Wednesday's Ellen DeGeneres Show, the 44-year-old actor joked that fatherhood "kind of screwed my career in a lot of ways."

"Because," he clarified, "I don't really care about it [my career] so much, because I care about her [Ava] so much."

"She's like No. 1 in my life," he added. "And now I get to do movies on the side. Daddy's my best role to date, I think."
